Serving the Industrial and Municipal Water and Wastewater Treatment industries for 36 years,
Custom Environmental Technology, Inc. is a leading supplier of specialty chemicals to a wide range of industries. These include: Municipal Wastewater Treatment, Potable Water Treatment, Food and Beverage Processing, Dairy Processing, Meat Packing, Mining and Quarry, and Metal Processing.

Aside from the municipal wastewater treatment plants that treat our domestic effluents, industries produce large quantities of wastewater during their production and processing of various goods.

Our complete line of specialty products enhance water clarification processes in these industries and makes it possible to recycle clarified water or to direct back harmlessly into our environment.

Specialty Chemicals: Coagulants and Flocculants
Coagulants and Flocculants are high efficiency chemicals designed specifically for solid-liquid separation of suspended solids in wastewater.

Conditioning the wastewater in removal of suspended solids requires chemical coagulation and flocculation. The idea of adding coagulants is to aid in the solid particles coming together to form a larger particle often called a “floc”. Flocculants are introduced
to gather up the smaller coagulated solids thus forming larger flocs of the suspended solid content in the wastewater. These larger floc particles will settle relatively quickly to the bottom, leaving clear water. The added flocculant does not stay in the water, but is attached to the solids. Solids are further processed and removed from the treatment environment.

Our primary specialty chemical line are Polyacrylamides or Polymers which are found in a wide range of molecular weights and charge densities. Different forms and grades of these flocculants are available for use depending on the application. Modern day wastewater treatment plants use these polymers to enhance clarification, as well as apply towards sludge thickening and sludge dewatering operations. Polymers are generally introduced into primary clarification treatment processes to increase solids settling, thus reducing loading to the secondary treatment. In many treatment plants the wastewater flows from primary clarification into the secondary area of treatment. The periodic addition of polymer into the secondary treatment operation can reduce solid handling and thicken secondary solids for further processing in sludge dewatering areas. Solids removed from wastewater by dewatering methods may be disposed of by composting, farm land application as a soil conditioner or fertilizer, burial in a sanitary landfill or incinerated.
