Dredging Lagoons: When to Do It and What are the Benefits?
Abstract: Desilting is the removal of sediments accumulated at the bottom of lagoons, reservoirs, and treatment systems. The accumulation is gradual and silent: the lagoon loses useful volume without anyone noticing, until the efficiency of the treatment decreases. The 5 main signs are: loss of treatment efficiency, bad odor, reduced depth, risk […]
Geobags: How They Work in Sludge Dewatering
Abstract: Geobag is a high-strength geotextile tube that retains solids while allowing water to pass through. The sludge enters with 90-95 liters of water and exits with a much higher solids content—drastically reducing the volume to be transported and disposed of. It is the lowest-cost alternative to centrifugation, but requires […]
UAP Hydroblasting: What is Ultra High Pressure and When to Use It?
Summary: UAP (Ultra High Pressure) is hydroblasting above 30,000 PSI, reaching up to 40,000 PSI. It is indicated for severe encrustations, coating removal, cold cutting, and surface preparation. It does not generate sparks—therefore, it is safe in classified areas with potentially explosive atmospheres. It does not replace lower pressure ranges: excessive pressure damages surfaces […]
NFPA 69 Inertization: How it Works and When it's Mandatory
Abstract: Inerting reduces the oxygen concentration in an environment to a level where combustion becomes impossible. NFPA 69 is the international standard that defines the parameters of this process—including the concept of LOC (Limiting Oxygen Concentration). It is mandatory whenever there are flammable vapors and a potential source of […]
