When chemical is used for the treatment of municipal drinking water and wastewater, or industrial process water and effluent, the expectation is that the chemical metering pump will be accurate and its measurements repeatable. However, even the most advanced pumps should be calibrated at the time they’re installed. Calibration is essential in maintaining process efficiency, ensuring safety, and for compliance with regulatory standards. This article explains the process.

When it comes to chemical treatment of water and wastewater, a chemical delivery system that provides precision, efficiency, and reliability is paramount. Purchasing a preassembled skid system avoids hassles and setbacks like having to source each component individually, such as pumps, flow meters, gauges, valves, and piping. Prefabricated and preassembled skid systems simplify installation and facilitate fast startup, which can significantly reduce installation time and help keep labor costs in check.

Many steps are involved in properly treating wastewater to meet regulatory requirements so it can be safely reused or discharged, and disinfection is a critical step. Disinfection kills or disables pathogens which may be harmful to humans, the ecosystem, or both. While chemical treatment with sodium hypochlorite is the most well-known and widely used, other technologies are being used successfully, including peracetic acid (PAA), ozone, and UV disinfection. How do you choose?

A variety of challenging chemicals are often needed in order to meet treatment goals for drinking water or wastewater operations. Precise dosing of these challenging chemicals, including polymers and caustic substances, requires a chemical metering pump that will ensure gentle and damage-free handling. There are a range of available technologies to help mitigate problems and ensure smooth, accurate, and dependable chemical dosing. This article discusses challenges and solutions.

Two types of chemical dosing pumps are most often considered for treating water or wastewater: diaphragm and peristaltic. In such critical applications the chemical feed unit must be both accurate and repeatable, and preferably simple to operate. The question is posed, which of these pump types, diaphragm or peristaltic, will perform most effectively and reliably in your chemical treatment application? This article gives insight into both pump types.

Turbidity is a simple and intuitive property of water. However, as easy as it may be to observe turbidity, the relationship between turbidity and water quality is not straightforward. With the right combination of knowledge and technology, treatment plants can keep turbidity low and properly disinfect both municipal and industrial wastewater prior to discharging, in addition to delivering safe, clean drinking water. This article will discuss how best to mitigate turbidity.
