The Leopold elimi-NITE(tm) Denitrification System uses the advantages of deep bed, mono-media filters to remove nitrogen in wastewater effluent. In addition to nitrogen, the system can simultaneously remove suspended solids. The gravity, downflow, packed-bed denitrification system is an attached growth, microbiological process which removes nitrate-nitrogen achieving levels below 1 mg/liter.

The Headworks Eliminator(tm) provides fine screening suitable for use in Membrane Bioreactor systems. The screening system installed upstream of the finer filtration systems and is designed to improve their performance. The stainless elements form a continuous band, which travels parallel within the channel. The water enters through the center of the screen, turns 90 degrees, passes through the stainless steel sieve elements, and exits through the sides of the unit. Screenings are captured by the elements and are carried up to the discharge point.

Industrial Test Systems has developed a new, safe ammonia test based on a modified Berthelot method. The test does not use toxic mercury salts or toxic phenol. This eliminates the potential hazards along with the inconveniences of handling dangerous chemicals and the foul odors that accompany them. The test readily has 0.1 mg/L sensitivity. A visual version currently allows detection at 0.2 - 3.0 mg/L as ammonia. Users simply dip one Ammonia ReagentStrip into a 2 ml water sample for 40 seconds with a gentle, steady up and down motion.
