Sewage treatment plants are characterized by high humidity, sudden temperature changes, ice formation, presence of corrosive substances (hydrogen sulfide, ammonia, organic sulfur compounds, reduced organic sulfur compounds, amines, indole and skatole, volatile fatty acids), viscous substances, biological reproduction of microorganisms and weeds. Thanks to their resistance to corrosion, moisture, low temperatures and sudden temperature changes, fiber plastic products offer an ideal solution to these environmental problems.
M.M. gratings are manufactured according to DIN 24537 – 3 and can be supplied non-slip according to DIN 51130 to ensure maximum safety for operators. We can also provide parapets to protect operators working near pools (sediment tanks, flotation tanks, sand collectors, oil separators, clarifiers, activated sludge tanks, thickeners, sterilization tanks). All M.M. the products are manufactured in accordance with UNI EN ISO 14122 – 1,2,3,4, standards and legislative decree 81/2008 on occupational safety. M.M. offers CE-marked ladders for control chambers that comply with the UNI EN 14396 standard. As a solution to the problem of bioaerosols, which are generated during the stages of wastewater treatment and can spread into the surrounding environment, M.M. offers its own covered gratings capable of isolating hazardous environments. Covered by M.M. gratings are made of dielectric materials and are certified as excellent insulators according to EN 61340-2.3 and IEC 61340-4-5 electrical safety standards. Therefore, they ensure adequate electrical safety.
