Service for municipal

We offer wide range services for Municipal waste water treatment:

Selection and supply of flocculants for sludge dewatering and conditioning with:

• Belt presses

• Centrifuges

• Filter presses

• Rotary drum thickeners

• Drying beds

 

Consulting and solving problematic cases, where usual polymers do not yield satisfactory results. Problematic cases can include:

• High index and bad dewatering properties of sludge.

• Complicated sludge treatment schemes where different flocculant types are involved on the same sludge (i.e. sludge thickening, mixing primary and excess sludge and final dewatering).

• 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.

 

Our Unafloc chemical range is specially designed for municipal waste water and sludge treatment processes. Unafloc chemicals have stable properties, high quality and are safe for health and environment in case of proper handling. For detailed safety information, please contact us.

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.

• Antiscalants

We offer professional service in chemical selection, supply and consultations.

• 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 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
