Pipeline Dewatering

We specialize in dewatering pipelines after a pressure test has been performed. The water is filtered to specifications so it can be returned into the environment. The filtration process removes particulates, heavy oils, PCBs, hydrocarbons, toxins and metals from the water. During the filtration process the water is tested before any ground release, and periodically to ensure that environmental specifications are being met. We can achieve filtration flow rates of up to 12 cubic meters per minute. Specific filtration requiring carbon will need slower flow rates to achieve proper filtration and contamination removal.

The first step in the process is getting the hydrotest water out of the pipe and into a storage tank for storage and processing. - Degasser Tank The hydro test water is pushed into the degasser tank from the pipeline via the pig and air pressure, the degasser tank is designed to separate the air from the water as it enters the tank, this also allows the hydrocarbons to rise to the top and the heavier solids to fall to the bottom of the degasser tank. This extends the life of the filters as well as the carbon reducing the filtration and carbon costs of the project.

Second step in the process is to filter the stored fluid from the degasser tank. We use a large pump to draw the water from the degasser tank and pumps it through the filtration vessels. Filtration Unit The filter bags trap the solids in the water. 

The 3rd step in the process is Carbon treating the solution – Carbon Bed The water from the filter trailer is pumped into the carbon beds, the water flows through the carbon removing the hydrocarbons and other impurities from the water. Once the water leaves the carbon bed it flows out through a discharge line to a diffuser.

The last step in the process is returning a clean and environmentally safe fluid back to the ground – Diffuser Filter cloth, plastic and other materials are laid down at the discharge of the diffuser, this is used to protect the surrounding soil from erosion. The clean filtered and reclaimed water from the carbon bed is pumped back to the environment where it originally came from.

Process Chemical Reclamation

JL Filtration’s Chemical Reclamation can eliminate problems related to dirty or contaminated process chemicals. Filtering your chemicals can reduce foaming, suspended solids and reduced wear on downstream pumps and equipment. JL Filtration’s filtering process will reduce the need to replace or add additional chemicals while increasing your existing filter service life.

Tying into the existing system using a slip stream process allows for reclaiming your chemical while the process is in service. No shutdowns are required, reducing the maintenance costs and increasing production.
