• Meat

Waste water generated from meat processing factories normally has high fat, BOD, COD, suspended solidsmany cases is too polluted to discharge directly to biological treatment. Meat production factories sometimes has own slaughterhouse which adds even more organic pollutants in common effluent.

Physico-chemical treatment often is used for primary treatment of meat factory effluent. Effluent from factory is gathered to pumping station (big waste before it is removed using various screens) where it is equalized that constant quantity of pollutants will be pumped to treatment equipment.

As treatment equipment often are used flotators or (in case fat is removed earlier by grease/fat remover) sedimentation tanks. Most common are flotators as they remove pollutants very effective and quickly.

For meat factory effluent primary treatment can be used alone or combinations of following reagents:

• Coagulants – organic cationic or non organic metal salt coagulants as coagulation aid.

• Flocculants – special brands of cationic or anionic polyacrilamydes that are perfectly soluble and have no lumps. Flocculants sticks coagulated particles onto surface making bigger flocs and thus helps to remove pollutants quickly.

• Bentonite clays -specially activated types of bentonite for high polluted effluents.

Coagulation quality depends on effluent pH. Organic coagulants and flocculants are effective over wide range of pH 2-10, but non-organic coagulants are best effective when pH is close to 7. It means that often pH adjustment is necessary before non-organic coagulants usage. As coagulants bentonite clays can be used very effective. Bentonite clays are effective over wide range of pH . In comparison with metal salt coagulants bentonite is quite safe for human health.

• Fish

Service for oil industry

Many industries discharge liquid waste contaminated with hydrocarbon or oil-like pollutants. Sources of such waste include petroleum and petrochemicals refining and processing, tramp oils from machine tool coolants, utility operations, sanitary sewage, bilge and ballast water, contaminated surface runoff.

Normally without correct reagents almost not possible to separate oil and water in oily emulsions.

 

Oil discharges into the environment typically have deleterious effects.

Here You will find information how the oil-in-water separation process can be enhanced and various oil separation systems can be run in effectively using POLIFLOCK and Unafloc reagents. Here is also evaluated the selection and design of a separation systems, presenting an up-to-date overview of technologies currently available and of their capabilities in terms of achievable discharge levels.

Service for paper industry

For paper industry we offer special Unafloc reagent brands that help to increase retention and dewatering on paper machine. Also our field of activity includes physical-chemical treatment of effluent from paper industry.

For those needs we offer the following:

• Chemical schemes for efficient effluent treatment.

• Laboratory and industrial trials.

• Consultations for applications of flocculants, coagulants, antiscalants, antifoamers and bacteria products

• Flocculant and coagulant selection for flotation systems.

• Flocculants – special brands of cationic or anionic polyacrilamydes that are perfectly soluble and have no lumps.

• Coagulants – organic cationic coagulants for retention aid. The allow fully or partially replace alum or other aluminium based salts in paper making process. These coagulants do not interfere on pH of the system.

• Bentonite clays -specially activated types of bentonite for paper machines.

Service for dredging

Our treatment decision can be very effective for dredging works. Small dosages of the synthetic & water soluble polymers drastically improve dewatering properties of dredged slurry.

This helps to save:

• Space and weight – because better dewatered slurry takes less space and weights less.

• Costs on environmental issues – because of cleaner leachate.

• Time – because dewatering after polymer addition takes much less time.

 

Our experienced team is ready to help You to solve problems related with dewatering of slurry. We are able to consult and supply high class of polymers specially designed for dredging applications.

 

Unafloc SM applications are especially important for high inhabited areas or with minimum of space available. It permits to implement dredging works in such places where it is impossible without use of properly selected polymers.

 

Main benefits by using Unafloc polymers:

• Smaller volume storage disposal areas can be used.

• Acceleration of particle settling, up to 100 times faster than that of natural means.

• Increased in-situ percent solids by weight this permits greater amount of sediment storage per unit volume of disposal area

• Increased clarity of de-cant water, especially when disposal area is greater than full.

• Polymers can eliminate the need for a second or third disposal area in series to clarify the decant water or smaller ones can be built instead.

• Polymers permit the use of carbon filter media for the decant water since the de-cant water is clearer and will not clog the carbon.

• Settling ponds can be re-cycled and cleaned during dredging by having 3-4 ponds to pump into.

 

The main dredging application where polymers can be applied:

1) Oxidation Ponds

2) Industrial Ponds

3) Lake Siltation

4) River Silt

5) Fly Ash

Service for chemical industry

Chemical industry effluent requires very carefull laboratory analysis. Normally effluent is primary treated and then let tcity’s network. In some cases additional biological treatment is required.

Chemical industry effluent normally has high BOD/COD, P, heavy metals, other dangerous chemical substances, which are neccessary to remove before discharge to city’s network. For primary treatment flotation or sedimentation is used combining these methods with variuous water treatment chemicals, which first must be tested in laboratory for efectiveness and doses. Primary treatment can remove approximately 50-70% of pollutants. If there is only biological treatment without primary treatment such system is very sensitive. When biological treatment is not effective it is possible to use variuous bacteria products than can intensify biological process.

For variuous problems in waste water treatment we offer:

• Determination of waste water process

• Primary treatment lab tests for specific pollutants

• Reagents determination, dosages fixing, evaluation of treatment process in laboratory

• Industrial treatment trials

• Start up works assistance

• Equipment delivery

• Phosphorus removal in primary or biological treatment

• N removal in aerotanks

 

• BOD/COD reducing

• Sludge dewatering assistance

• Fats removal

• Oily water treatment

• Colour removal

• Deemulgation of oil

• Suspended particles removal

Lime inhibitors

Poliflock anti-limescale products prevent the formation of deposits from Ca, Mg, Fe, etc. of salts.

Poliflock anti-limescale agents work at pH above 6.5 at normal or high temperatures – up to 100 °C.

Poliflock prevents the formation of scale deposits at every stage of the production process, thus simultaneously preventing the formation of scale in many industrial processes.

The use of limescale protection is very simple: the product is added with a dosing pump, as is or as a 10% solution. The material should be added to the hard water or piping as early as possible so that it is mixed as effectively as possible throughout the volume.

For ease of use, limescale inhibitors are available as a stock liquid, or as a ready-made solution if needed.

Demulsifiers

Oil separation by gravity plays important role in ports or oil refineries. Heated tower separators are usually used. When oil emulsion is stable even after long time heating it is difficult to achieve good results: oil separation is poor and oil fraction contains a lot of water. After addition selected emulsion breaker, gravity separation goes much more quickly and efficiently.

Ecochemicals company consults, makes selection and offers the following products for gravity separators.

Usually stable oil emulsions can contain up to 40 -60 % of water. After adding Unafloc emulsion breaker it is possible achieve 5 to zero % water content in oil. 

 

Bentonite sorbents

We offer bentonite sorbents, which are used in many applications
areas such as drinking water treatment, industrial wastewater treatment,
for juices, beverages, food industry, wells.

Bentonites are in powder form.

It is a non-toxic product.

Bentonite sorbents effectively remove BOD, COD, dyes,
heavy metals, colloids, Cr removal, etc.

Special tools must be used for injection of bentonite solution
anti-abrasive pumps.

Antifoamers

During wastewater treatment, foaming may occur when surfactants are present on the surface

Thus, wastewater can be divided into 3 types, depending on its source:

(a) Industry: high-foaming “synthetics” such as from detergents, soaps, emulsifiers, disinfectants, etc.

b) Industry: foam stabilizing “natural” materials such as starch, protein, fiber, cellulose and other long chain polymers.

c) Municipal: very dilute mixtures of surfactants. Also composted sludge, which contains less active foaming agents. Foam

occurs wherever air enters or gasses the wastewater. By reducing the free fall of liquid from pipes or

partitions etc. reduces slight aeration, but the nature of certain processes inevitably creates conditions for the formation of foam,

which may require control or suppression

Foaming is a problem in many different industries and areas:

• Sugar industry

• Dairies

• Fermentation processes

• Vegetable processing

• Paper production

• Activated sludge processes

• Primary mechanical aeration

• Other processes

We offer a wide range of antifoams.

Flocculants

Organic flocculants are widely used for many waste water, drinking water, polluted liquids treatment. Also dewatering of variuous sludges is almost impossible without flocculants usage.

Flocculants can be solid or liquid.

Normally flocculants are used in variuous application:

  • Sludge thickening
  • Sludge dewatering
  • Effluent treatment

We propose Unafloc range products which are anionic or cationic, low-medium-high molecular weight.

Applications area can be very wide and flocculants are used in :

  • Dredging
  • Variuous sludge dewatering
  • Drinking water treatment
  • Industrial polluted waters treatment
  • Sludge thickening in various processes
  • Municipal sludge conditioning

Dewatering

The term “dewatering” is understood as the removal of water from a mixture, suspension or emulsion, thereby obtaining a solid or liquid fraction with a lower water concentration.

Dewatering is used in many industries. Sometimes the dewatered materials are a valuable product (for example, in the paper, mineral or oil industries); in other cases, the water itself has the greatest value (as in municipal wastewater treatment operations).

However, regardless of the industry or equipment used, the key factors to consider are:

Water quality after drainage

  • Amount of water collected during draining
  • Dryness of the drained material
  • Quality of drained material

For industries such as paper, oil or minerals, the importance of the above factors is turned upside down.

A variety of equipment can be used for dewatering operations,

Dewatering equipment using UNAFLOC brand chemicals:

  • Centrifuges
