How a polymer dosing system can make or break your sludge dewatering process.
Polymer is the secret ingredient for maximizing dewatering and achieving high quality filtrate from the Geotube® containers in our Bishop Solids Management Solution. But selecting the right polymer is not enough to get the best results.
Precise dosing is critical to ensure that the operation runs smoothly and that dewatering occurs as required without any unfortunate incidents. Not enough polymer will result in poor dewatering performance, insufficient solids retention and low-quality filtrate. Too much polymer can clog the pores of the Geotube container and prevent water from being released. In such a case, the bag is no longer usable and could burst if operators fail to notice the problem and overfill the container.
Bishop Water’s VEPAS™ (Venturi Emulsion Polymer Activation System) is an easy-to-use and affordable system that mixes and fully activates liquid polymer emulsions in a single step, adds the precise dose directly into the sludge feed line and eliminates the need for messy mechanical mixers and bulky aging tanks.
VEPAS Polymer Dosing System
Compact size, smart controls
VEPAS polymer dosing can be configured to monitor sludge flow and consistency using flow and mass meters, enabling it to automatically adjust polymer dose to achieve the optimum mix and dewatering properties. These smart controls also communicate with 4-20 mA inputs, which enables VEPAS to be integrated to the plant SCADA system and configured to automatically begin operating when sludge pumps are activated.
The compact, skid-mounted VEPAS occupies a fraction of the space of a conventional mechanical polymer system and can be quickly installed for new or retrofit applications in treatment plants, mobile trailers, or utility buildings.
Our Bishop Solids Management Solution with Geotube® dewatering technology and VEPAS is an integrated solution that can work with any wastewater treatment plant or industrial process to collect and dewater slurry materials. This enables any facility to build a compact, rapid dewatering solution that saves time, reduces operating costs, and simplifies sludge management.
A simple test can help us determine precise dosing of the polymer selected for your site and build a skid-mounted system that can be installed quickly. Once installed, our team can provide onsite training and are easily accessible to assist with ongoing maintenance and support.
