The Village of Johnson Wastewater Treatment Facility (WWTF) was among the first in the state of Vermont to meet newly enacted secondary treatment requirements when it began operation in 1970.
Publicly Owned Treatment Works (POTWs) are faced with the challenge of processing the effluent wastes of multiple sources: residential, industrial, and environmental. Under laws governing pretreatment, the ultimate responsibility in determining whether or not industrial effluent meets criteria for treatment belongs to the POTW. Once the POTW has the effluent waste within the confines of its treatment facility, it is accountable to the federal, state, and local regulations governing the quality of the wastewater it discharges into lakes and streams or injects underground.

Turbidity, a measure of the cloudiness or haziness of a fluid, was originally intended as a qualitative measure of the aesthetics of drinking water. It is not a measure of actual particles in the water; it measures how much those particles affect light being transmitted through the water, or how that light reflects off particles in the water. Today’s turbidity designs and methods have been regimented in an attempt to bring quantitative consistency to the measurement for both aesthetic and pathogenic qualities of drinking water.
In this second edition of Disinfection Digest, we will cover the physio-‐chemical properties of VigorOx WWT II peracetic acid.
Proper operation of water treatment processes depends on accurate flow measurements. Also, flow data is often required by regulatory agencies.
A renowned pharmaceutical company in Pune, India, installed a water treatment system to recycle pharmaceutical process wastewater for reuse. Ultrafiltration was chosen as pretreatment to a reverse osmosis system, and the feed water was tertiary treated pharma effluent. Soon after operation began, the existing UF membranes were repeatedly choking, and QUA offered Q-SEP ultrafiltration modules to the customer to replace the existing UF membranes.
Mississippi Power Company had a wide range of environmental considerations when they set out to choose a builder for a Zero Liquid Discharge (ZLD) system, integrated gasification combined cycle (IGCC) power plant. Aquatech was selected due to the company’s proven success in providing cost-effective, environmentally-focused water treatment solutions for the power industry. This case study provides details and technical specifications on the system selected.
