Engineered Solutions
Pure Water Treatment Service
With the company experience of four decades in the water treatment and the high specialization of our engineering staff, Unidro can propose for every project an optimized combination of process steps to make the water available at site suitable as Cooling Water, boiler feed water and process water in the industries.
Waste Water Treatment and Reuse Service
With a wide experience in the treatment of industrial wastewater and the knowledge to treat difficult process streams, we can match the most demanding regulations worldwide and handle the critical problem of water reuse.
Produced Water Treatment Service
With experience in water treatment, a wide separation equipment portfolio and a specific know-how on wellhead processes Unidro is a highly qualified partner for PWT.
Condensate Recovery and Treatment Service
Our experience in the water treatment and utilities combined with the wide range of technologies and equipment available in-house, give us a full coverage of the different needs connected to condensate treatment and recovery.
Lean Amine Treatment Service
Alkanolamines such as MDEA or DGA are solvents of common application in gas sweetening plants. Treating a slip stream of the circulating lean amine prevents undesired contaminants, such as suspended solids or amine degradation products, from being accumulated in the circuit. A lean amine filtration package would typically include three filters arranged in series: a pre-filter, to remove suspended solids such as iron sulphides or oxides; an activated carbon filter, to adsorb organic molecules generated by amine degradation; a guard filter, to avoid that any carbon fines would go through. Unidro has provided very large Lean Amine Filtration Units for highly demanding Clients.
Brine Purification Service
In chlor-alkali production plants based on membrane electrolysis, the feed sodium chloride (or potassium chloride) brine must be treated to a very high quality i.e. no suspended solids and very low residual hardness is admitted (few ppbs of calcium, magnesium, strontium). Unidro has a wide record of experiences in designing and supplying tailor made units for each of the main sections of the brine treatment chain: clarification of the saturated brine, filtration of the clarified brine, super-purification of the filtered brine by means of chelate resin towers.
Water Injection Service
In the “water flooding” or “water injection” process the water is injected into the oil producing rock displacing oil towards a second well where the oil is extracted. The fresh water which have to be injected needs to be thorouly treated in order to prevent wells plug. The treatment may involve removal of oil traces, suspended solids and oxygen, as well as chemical conditioning.
