ABOUT US

FIRMBASE PTE LTD, a Singapore-based company, was established by its founder Mr CT Pung in 2011 with the Mission to explore development opportunities in advanced materials to meet the growing needs on water, energy, and infrastructure.

FIRMBASE has invested and partnered with a leading specialty chemical company in China to develop, manufacture, and market of advanced polymers globally. It has its own polymerization development capabilities and manufacturing facilities in China, and international sales and technical support in Singapore.

In the Water Industry, in collaboration with the Environmental & Water Technology Centre of Innovation (EWTCOI) of Singapore, Firmbase has:

  1. Successfully developed a proprietary polymer based PVDF UF membrane with increased membrane pure water throughput, lower energy-saving operations, and lengthen operations uptime.

  2. Acquired a super hydrophilic polymer and membrane technology license that handles up to 100ppm of oil for oil-water separation with high reliability and operations uptime.

FIRMBASE has commercialized the proprietary polymer for PVDF UF membrane, with the refocus on the polymer development, the commercialization of the PVDF UF membrane is rescheduled to end 2020 and the oil-water separation products by 2021.

Aside from being a material supplier, FIRMBASE is also seeking partnership in terms of joint development, strategic market participation, or distributorship to bring these technologies and products into the various geographical markets.

MEMBRANE ENABLER

Polyvinylidene Fluoride (PVDF) ultrafiltration (UF) membranes are being widely used in water and wastewater treatment due to their excellent chemical and mechanical stability. However, the major shortcoming of these membranes is their strong hydrophobicity resulting in rapid flux decline and frequent back-flushing requirements which will shorten the life span of the membranes. Therefore, it is very important to enhance the hydrophilicity and mechanical strength of PVDF membrane. A common industrial practice to improve the hydrophilicity of PVDF is to add in hydrophilic additives such as polyethylene glycol (PEG) or polyvinyl pyrrolidone (PVP) into the dope solution. However, the main drawback of this methodology is that, these hydrophilic additives are highly water soluble and hence, over time, the hydrophilicity of the PVDF membrane will be reduced. FIRMBASE’s hydroxyl functionalized polymer (4483) is added to solve this problem.

The hydroxyl functionalized polymer (4483) enables the formation of hydrogen bonds with water and thereby enhanced the permeability of the membrane. The monodispersed and highly branched macromolecules structure of this specialty polymer provides improved porosity and pore size distribution in the membrane for improve mechanical strength and anti-fouling. Lengthening the operations uptime of the membrane, increasing the clean water flux, and reducing the energy requirements.

1. Clean Water Flux (LMH/bar)) increased by >25%

2. Operating Pressure (bar) reduced by >33%

3. Contact Angle (degree) reduced by > 15%

COMING SOON

FIRMBASE has acquired a super hydrophilic polymer and membrane technology license for oil-water separation to provide a reliable and high operations uptime membrane solution from Environmental & Water Technology Centre of Innovation (EWTCOI) of Singapore.

FIRMBASE is in the process to scale up the polymer by end-2020 and the membrane to be available in 2021.

FIRMBASE is also seeking partnership in terms of joint development, strategic market participation, or distributorship to bring these technologies and products into the various geographical markets.
