Sewer collapses due to sulfuric acid corrosion. Thioguard can help.

 

ThioguardŽ

THIOGUARDŽ, offers a safe, cost effective and environmentally responsible strategy for prolonging infrastructure life, managing odor, preventing plant upsets, improving treatment, and enhancing the quality of biosolids. It is the Total System Treatment (TST) solution.

In fact, THIOGUARDŽ is probably the most significant development in wastewater management in the last 30 years. It is non-hazardous, it is affordable ... and it works.

What is ThioguardŽ?

THIOGUARDŽ is a gentle, bio-receptive mineral nutrient and alkalinity source that gently reduces both corrosion and odor throughout sanitary sewer systems while enhancing many treatment plant processes.

THIOGUARDŽ offers benefits at every point in the wastewater system. When added directly to wastewater, it slowly dissolves to buffer the pH of the water, thus significantly decreasing the amount of hydrogen sulfide (H2S) produced and reducing odors. When used as a protective spray on concrete sewer crown and manhole surfaces, THIOGUARDŽ efficiently neutralizes the corrosive effects of sulfuric acid and Thiobacillus bacteria that attack concrete. THIOGUARDŽ protection slows the aggression of these corrosives and result in dramatic savings in sewer line replacement and rehabilitation.

In fact, THIOGUARDŽ's effectiveness is unsurpassed. Not only does it control odors by reducing both dissolved sulfide production and H2S (headspace) gas, it also offers additional benefits as well. For example, the introduction of H2S does not lead to the formation of additional unwanted sludge, as often happens with lime and iron salts. What's more it exhibits long retention times, maintaining buffered pH more consistently than other treatment options.
