Clean Water Act Impacts Concrete
The Clean Water Act impact on concrete producers: An Explanation and Solution When the Clean Water Act was enacted, one of the intentions of this legislation was to reduce the untreated industrial wastewater burden on Publicly Owned Wastewater Treatment (POTW) plants in the same manner that industrial wastewater would only load the treatment plant to the same extent as ordinary household...

2011 – 2012 CASE STUDY Sludge Set™ Used To Solidify a Cementitious Heavy Slurry at a Concrete Paving Operation Fortrans Inc. became involved in a concrete paving project by providing a pH control system to treat high pH gray water. The pH system lowered the pH of the process water to 7.5 and lowered Total Suspended Solids to <30 mg/L to ensure the water met all EPA requirements for safe...
Read MoreLowering pH to minimum of 6.5
Case Studies in Progress: Lowering pH to minimum of 6.5 in very high temperature water with moderately high pH at 5,000 GPM flow with carbon dioxide. Lowering pH levels in water derived from filter press applications with carbon dioxide at fixed base operations and mobile in field or on the go treatment.

CASE STUDY 3 – High Temperature – High pH Water A large terminal operations company in the Midwest wanted to use carbon dioxide for pH control of boiler blow down water to see if they could achieve a cost reduction and greater safety by replacing a sulfuric acid treatment process with one of Fortrans Model 5000SK pH Control systems. The pH of the boiler blow down water was 12.0 at a...

CASE STUDY 2 – High pH – High Total Suspended and Dissolved Solids A ready mix concrete manufacturing operation needed to neutralize high ph process water resulting from rinsing of the interiors of concrete delivery trucks and rinsing of the exteriors following the loading process. The purpose was to be able to discharge excess process water and or storm water that drained into the...

CASE STUDY 1 – Extremely Low Alkalinity and Moderately High pH An open pit taconite mining operation in Minnesota had a problem with high pH groundwater infiltrating into the mine and the water had to be pumped out 24 hours per day to be able to continue mining operations. The high pH was a result of an alkaline blasting agent used to fracture the ore bearing rock so it could be mined. Some...
