The former covers treatment of water for potable or industrial use and the latter treatment of domestic and industrial wastewater for reuse or disposal complying with local environmental agency standards.
GNH ESI consultants are sought after for projects requiring local know-how in standards specific to the area, materials sourcing, integration and project management. Below are examples of projects and services GNH principals have implemented in the past with a long list of references. The Company services operations worldwide and covers a diverse range of industries, including Chemical, Pharmaceutical, Petrochemical, Semi-Conductor, Steel, Toiletries, Food and Beverage and Marine. GNH ESI may, when necessary, conduct treatability studies based on pilot testing on a fractional flow.
Membrane-based systems
GNH ESI serves municipal and industrial clients for both pure water generation and effluent treatment. Polymeric and ceramic membranes specific for the treatment process utilizing different molecular cutoffs and configurations of Revere Osmosis (RO), Ultrafiltration (UF), Microfiltration (UF) and
Chemical, physical and biological effluent treatment systems
GNH ESI works with the local environmental agency and the client to design and supervise building the right system, complying with disposal standards or recycling for reuse. Applications cover domestic sewage and industrial effluent treatments. The former typically uses a biological process based on Activated Sludge (AS/EA), Sequential Batch Reactor (SBR), Membrane Biological Reactor (MBR) or Moving Bed Biological Reactor (MBBR). Industrial effluent, on the other hand, may use a combination of the biological processes in conjunction with chemical reactors and the membrane processes listed above. Sludge dewatering devices such as centrifuges, filter and belt presses are selected based on consistency, volume and desired dry mass.
Ballast water management system
GNH ESI’s expertise and collaborating team of experts assist shipowners in selecting and retrofitting the right treatment process. Invasive Aquatic Species in a ship’s ballast water is one of the biggest problems faced by the shipping industry. Under the IMO’s “International Convention for the Control and Management of Ship’s Ballast Water and Sediments ”, implementation of ballast water management plan and ballast water treatment system on board ships has become important. After years of discussion, the IMO’s Ballast Water Management Convention went into effect on September 8th, 2017. For operators with vessels that discharge ballast water in international waters, this means they must have a treatment system installed on their vessels within five years. With the ratification of the Ballast Water Management Convention, shipowners have been pressed to decide which treatment systems to choose – a solution provided by GNH.
