Our main water chemicals

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 applications.

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.

Coagulants

Coagulants are first aid in chemical water treatment. They can be

non-organic, organic or mixes of organic and non organic coagulants.

Coagulants can be solid or liquid. It is possible to use coagulants for dissolved pollutants treatment, heavy metals, COD, BOD, phosphorus, etc. removal.Coagulants mostly are used together with flocculents to ensure the best treatment result.

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

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. 

 

Coagulants

Coagulants are first aid in chemical water treatment. They can be non-organic, organic or mixes of organic and non organic coagulants.

Coagulants can be solid or liquid.

It is possible to use coagulants for dissolved pollutants treatment, heavy metals, COD, BOD, phosphorus, etc. removal.

Coagulants mostly are used together with flocculents to ensure the best treatment result.

• Strong influence from industry that disturbs normal sludge treatment process (as often cases with sugar mills or diaries in smaller towns).

• Other difficult to detain reasons, why flocculants do not work well (it can be because of inappropriate preparation water, specific compounds in sludge, wrong flocculant type and etc.)

 

Consulting and selection of physical-chemical waste water treatment schemes for municipal WWTP. This includes:

• Phosphorus reduction

• BOD/COD reduction

• Suspended solids reduction

• Heavy metals elimination.

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

6) Atomic Wastes

7) Paper Mill Sludge

8) Sugar Beet Waste Washings

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.

• 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 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
