Urbanisation and population growth increase the amount of water used for maintaining various activities in the residential, commercial and industrial sectors. Consequently, the volume of waste water increase pose a new challenge for wastewater treatment systems. The concrete infrastructure of wastewater treatment systems is subject to complex physical stress and chemical corrosion processes. MasterSeal 7000 CR from BASF is specifically designed to address these challenges.

The complex nature of wastewater treatment and its degradation process creates challenging environment for the surrounding infrastructure. The rate of chemical attack depends on various factors related to the conditions in both the wastewater and the environment where the pH level can decrease to below 1 in some cases.

MasterSeal 7000 CR: Meet the challenges of aggressive wastewater environments
MasterSeal 7000 CR is the waterproofing and concrete protection system with a unique combination of application and performance properties that meet the challenges of aggressive wastewater environments. Based on the new innovation XolutecTM technology which enhanced overall material properties, MasterSeal 7000 CR is formulated with high resistance to abrasion and biogenic sulfuric acid (BSA) corrosion is ideal to withstand the severe conditions in wastewater treatment tanks. The performance proven MasterSeal 7000 CR system significantly extends the life cycle of concrete structures by protecting against biogenic concrete corrosion.

An ideal solution for waterproofing
MasterSeal 7000 CR‘s fast and easy application by rolling or spray, as well as its excellent curing properties allow the efficient, safe and continuous operation of wastewater treatment infrastructures.“High chemical resistance and its ability to bridge cracks of up to 0.7 mm make MasterSeal 7000 CR the ideal solution for waterproofing and protecting wastewater treatment concrete structures and sewers. MasterSeal 7000 CR has been tested under real conditions that simulate those of a real sewer for five years and results of the test show no changes on the properties of MasterSeal 7000 CR,” claims BASF.

Applications
MasterSeal 7000 CR is ideal for application in pretreatment, sedimentation, aeration tanks and sludge, or sewers to protect the concrete structures from physical and chemical corrosion particularly biogenic sulfuricacid (BSA) corrosion. The easy application of MasterSeal 7000 CR by spray or roller, as well as its compatibility with damp substrates suit the conditions of wastewater facilities particularly well.

Downtime, which is always critical when stopping wastewater treatment process, is also reduced because MasterSeal 7000 CR is fast curing and can be contactable with water 24 hours after application at 20 C.

Growing commitment to environmental protection and sustainability, as well as the cost of water, have led to an increased need for the treatment of urban wastewater and reuse of water at industrial plants. As a reliable partner, Master Builders Solutions by BASF helps the customers to protect the durability of their assets and operations without unexpected downtime. Because it isall about the main element of life: water.
