Suspended solids meter
Easily measure the concentration of sludges or slurries without the reading being affected by color using the Markland Model 502 Suspended Solids Meter. It uses the attenuation of ultrasound to read the concentration. The meter can be mounted in open top tanks or pipelines. It measures slurries that are too thick for optical methods. Ultrasound is inherently safe so it requires no permits or regulatory approvals to operate.

Sodium hypochlorite
Severn Trent Services recently introduced a new skid-mounted ClorTec On-site Sodium Hypochlorite Generating System. The new system integrates the company’s on-site generation technology into a pre-packaged design that can be installed and producing hypochlorite in less than one day. On-site generation is a cost effective, reliable and safe alternative to chlorine gas and bulk sodium hypochlorite. The ClorTec systems range in capacity from 6 to 3000 pounds per day, generating a 0.8% sodium hypochlorite solution by combining three common consumables: salt, water, and electricity, to produce a chlorine equivalent.
