Waste Water Treatment

A number of trends are driving demand and innovation in the water-treatment industry, including an increasing level of regulation, the drive for cost reduction, reducing the volume of chemicals used in treatment, and environmental aspects such as energy consumption and discharges.

Contro Valve offers the products of a wide variety of manufacturers to meet some of these challenges, including:

• MSA’s comprehensive line of fixed gas detection products continuously protect workers and contractors in the treatment plants. Areas of the plants that are subject to flooding such as wet wells and influent headworks, are ideal for MSA's Tri-Gas Monitor sample draw custom system. The system is ideal for monitoring oxygen, hydrogen sulfide and combustible gases (methane). In addition, the system is specifically designed for optimum performance in high-moisture environments. The TriGard Gas Monitor detects chlorine, sulfur dioxide, other toxic gases, remote combustible gases, and oxygen deficiency or enrichment. These monitors are designed specifically for water and wastewater applications.
• Galvanic Applied Science’s continuous, real-time, on-line liquid-analysis products give you peace of mind to help avoid cataclysmic events before they happen: they’ll alert you the moment parameters are not meeting specifications so you can be proactive to remedy the situation. For example, their Monitek optical-technology-based turbidity, suspended solids, and color monitor delivers the highest performance-to-cost ratio of any in-line liquid process monitor on the market today.
• ABZ manufactures a series of high performance butterfly valves in large diameter sizes that are appropriate for both manual or automated actuation for water treatment applications. Their 396/387 series valve is a molded in seated valve that is ideal for where chemical or abrasive resistance is required.
• Richter Chemie-Technik GmbH line of high quality fluoropolymer lined valves can be a good choice for some of the aggressive conditions encountered in wastewater treatment.
