Low temperature Anaerobic Digestion - Brewery/Malting Industry

NVP Energy （NVPE）开发了一种独特的技术，可以将废水（WW）净化到非常高的标准，同时回收有价值的高质量沼气，100%可重复使用。NVPE的解决方案具有全球影响力，其创新的节能“低温厌氧消化（Lt AD）技术”可在低于20摄氏度的温度下工作（这是厌氧消化的独特之处）。NVPE的解决方案将废水处理（WWT）从运营成本转变为食品和饮料行业（酿造、麦芽酿造、蒸馏、装瓶、乳制品、肉类加工）的潜在客户的新收入来源，平均投资回收期为3年。Lt AD提供了三重效果：大幅降低60%以上的商业污水收费，去除污泥，并产生100%可重新利用的沼气，在现场产生热量或电力。污水处理发生在环境温度下，所以微生物有效工作不需要热量输入。较低的处理温度不会影响该技术的效率，使Lt AD在水力保持时间低于12小时的情况下工作。NVPE的创新使客户能够在现场处理大量低强度WW，该技术可以去除WW中的化学需氧量（COD）和总悬浮固体（TSS）浓度，使客户能够显着降低当前的贸易废水费用。与其他污水处理技术不同，产生的污泥可以忽略不计，因此污泥处理和处置成本最低。Lt AD过程的副产品是沼气，由于沼气产生的能量大于运行系统所需的能量，因此它是碳中和的，并且是积极的。产生的沼气（CH4含量超过80%，H2S含量非常低，这对于AD来说是非常特殊的）可以通过锅炉或热电联产系统在现场100%用于供热和/或发电，这将成为客户持续的收入来源。NVPE将为在酿造麦芽应用中使用Lt AD开发一个强有力的商业案例，这是一个关键的目标市场，因为WW的低强度特性和现场产生的大量WW。对于这个业务案例，NVPE将选择最合适的最终用户，在他们的一个“现场”操作站点上部署一个全尺寸演示器。NVPE已经与潜在客户进行了接触，反馈表明，在他们考虑进行全面的商业部署之前，下一步是在他们的行业中建立一个持续运行的参考站点。在第一阶段，NVPE将根据一系列标准选择最终的第一个采用者客户和选定的站点。第二阶段NVPE将设计、安装、调试和运行一个全尺寸演示系统，每天处理500立方米，在酿造麦芽现场，以全面验证该技术在目标市场的全面应用。最终结果将证实NVPE的短期回报和价值主张计算已经在实验室和试点规模上实现，通过展示大规模的WW污染物去除和沼气质量量的一致操作数据。这个旗舰参考网站将使潜在客户能够亲眼看到处理其特定WW流的技术，为NVPE提供一个创造真正就业、收入和增长的平台。我们的技术适用于超过106家英国工厂，平均规模的工厂至少需要4个NVPE模块。投资回收期为2.5年，没有RHI投资回收期不到3.2年，为这个目标市场提供了一个令人信服的主张。

NVP Energy (NVPE) has developed a unique technology that cleans wastewater (WW) to a very high standard whilst recovering valuable high quality biogas that is 100percent available for reuse. NVPE’s solution has global reach, where their innovative energy positive ‘Low temperature Anaerobic Digestion (Lt AD) technology’ works at temperatures less than 20C (unique for Anaerobic Digestion). NVPE’s solution turns wastewater treatment (WWT) from being an operational cost into a new revenue stream for prospective customers in Food and Drink Industries (brewing, malting, distilling, bottling, dairy, meat processing,) offering average paybacks of 3 years. Lt AD offers a triple effect of substantially reducing trade effluent charges by more than 60percent, removing sludge and creating biogas that is 100percent available for reuse to generate heat and or electricity on site. WWT occurs at ambient temperatures, so uniquely no heat input is required for the microbes to work effectively. The low treatment temperatures do not affect the efficiency of the technology, allowing the Lt AD to work at Hydraulic retention times below 12 hours. NVPE’s innovation enables customers to treat their the large volumes of low strength WW on site, the technology removes chemical oxygen demand (COD) & total suspended solids (TSS) concentrations in their WW, allowing customers to significantly reduce their current trade effluent charges. Unlike other WWT technologies, negligible sludge is produced, so sludge treatment and disposal costs are minimal. A byproduct of the Lt AD process is biogas and as the energy generated from the biogas is greater than the energy required to operate the system, it is carbon neutral and energy positive. Biogas generated (more than 80percent CH4 content with very low H2S content, which is exceptional for AD) can be 100percent utilised on site for heat and/or electricity production through Boiler or CHP systems, which will become an ongoing revenue stream for customers. NVPE will develop a strong business case for the use of Lt AD in a brewing malting application, a key target market due to the low strength WW characteristics and large volumes of WW generated on site. For this business case NVPE will choose the most suitable end user to deploy a full scale demonstrator on one of their 'live' operational sites. NVPE has engaged with prospective customers and feedback has been that a consistently operating reference site in their industry is the next step before they would consider proceeding with a full scale commercial deployment. During Phase 1 NVPE will select a final first adopter customer and chosen site based on a number of criteria. Phase 2 NVPE will design, install, commission, operate a full scale demonstrator system, treating 500m3 per day, on a brewing malting site to fully validate the technology in this target market at full scale. The ultimate outcome will substantiate NVPE's short payback & value proposition calculations already achieved at lab and pilot scale by demontrating consistent operational data for WW pollutant removal & biogas quality volumes at scale. This flagship reference site will allow prospective customers to see first hand the technology treating their specific WW stream providing a platform for NVPE to generate real jobs, revenue & growth. There are more than 106 UK plants where our technology is applicable with the average sized plant requiring 4 x NVPE modules minimum. The payback is 2.5 years with RHI and without RHI the payback is less than 3.2 years, offering a compelling proposition for this target market.
