    Abstract: A filter medium is backwashed to cleanse it of cake when a fluid pressure difference across the filter medium rises to a predetermined degree. Since the pressure difference is subject to change not only with the amount of the cake but also with the temperature and flow rate of the fluid being filtered, not only the pressure difference but also at least either of the fluid temperature and flow rate is constantly monitored. A correction coefficient circuit is provided which has stored thereon pressure difference characteristics at various temperatures and/or flow rates of the fluid including a pressure difference at a rated temperature and/or rated flow rate. The correction coefficient circuit computes a correction coefficient by comparing the pressure difference characteristic at the monitored temperature and/or monitored flow rate of the fluid with the pressure difference characteristic at the rated temperature and/or rated flow rate of the fluid. A correction circuit corrects the monitored pressure difference by the correction coefficient in order to obtain a pressure difference at the rated temperature and/or rated flow rate. The filter medium is backwashed when the corrected pressure difference rises to a predetermined value.

    Abstract translation: 当过滤介质两端的流体压差上升到预定的程度时，过滤介质被反冲洗以清洗滤饼。 由于压力差不仅随着滤饼的量而变化，而且随着被过滤的流体的温度和流速也发生变化，不仅不断地监测流体温度和流速中的至少一个压差， 。 提供一种校正系数电路，其存储在包括在额定温度和/或额定流量下的压力差的流体的各种温度和/或流速下的压差特性。 校正系数电路通过将流体的监测温度和/或监视流量的压差特性与流体的额定温度和/或额定流量下的压差特性进行比较来计算校正系数。 校正电路通过校正系数来校正所监测的压力差，以获得在额定温度和/或额定流量下的压力差。 当校正压差上升到预定值时，过滤介质被反冲洗。

    Abstract: In a system having a fluid filter that is automatically backwashed each time the differential pressure thereacross reaches a predetermined value, the desired base rate at which the drop across the filter should increase during its initial filtering sequence (i.e., before backwash) is determined and stored in digital format in a process controller along with a preset maximum differential pressure at which backwash is set to occur. During use of the filter the actual rate of change of the pressure drop thereacross is monitored continuously and compared with the rate that is stored in the controller. Whenever the actual rate of change of the pressure drop across the filter differs from the base rate, which is the usual case, the present backwashing pressure is automatically adjusted--usually downwardly. This reduction continues until the actual drop across the filter finally reaches the adjusted value of the preset backwashing pressure, at which time backwashing of the filter is automatically commenced. In a preferred embodiment, the adjustment is based upon the time differential at a given instant between the actual filter time and the desired or base curve time, and the difference is used to reduce the preset pressure in accordance with the inverse of the base curve rate. In another embodiment the difference between the actual differential pressure across a filter and the desired differential pressure at any instant is determined and subtracted from the preset backwashing pressure.

    Abstract translation: 在具有流体过滤器的系统中，每当它们的差压达到预定值时，自动反冲洗，则确定并存储过滤器过滤器在其初始过滤顺序期间（即，在回洗之前）应增加的所需基本速率 在处理控制器中以数字格式以及设置发生回洗的预设最大压差。 在使用过滤器期间，连续监测压差的实际变化率，并将其与存储在控制器中的速率进行比较。 每当过滤器上的压降的实际变化率与基本速率不同时，通常情况下，本反冲洗压力通常是向下调整的。 这种减少持续到直到过滤器的实际落差最终达到预设反冲洗压力的调整值，此时自动开始过滤器的反冲洗。 在优选实施例中，调整是基于在实际过滤时间与所需或基本曲线时间之间的给定时刻的时间差，并且该差用于根据基本曲线速率的倒数来减小预设压力 。 在另一个实施例中，确定过滤器上的实际差压和任何时刻的期望压差之间的差异，并从预设的反冲洗压力中减去。

    Abstract: A liquid (2), such as wastewater, is filtered using a liquid-permeable filtering element (9) having first and second faces (10, 11) so as to produce filtered liquid (4) having total suspended solids of no more than 10 mg/L. The method comprises cycling the liquid-permeable filtering element through the liquid whereby, in a first position, an area of the first face of the filtering element is subjected to liquid under pressure and a pressure across the filtering element is greater than 0 and less than or equal to 5.9 kPa (60 cm H2O), and, in a second position, the area is not subjected to liquid under pressure or is subjected to liquid at a lower pressure, and solids accumulated on the first face of the filtering element can be removed by directing at least one jet at the second face of the filtering element through the filtering element towards the first face.

    Abstract: The present disclosure relates to a carbon capture adapter that may attach to high air flow systems. A carbon capture adapter may utilize the air flow foundations of a high air flow system to allow for capture of unfiltered ambient air, allowing for carbon removal and the scrubbing of the unfiltered ambient air. The carbon capture adapter may comprise of carbon sensors that may detect carbon levels of the air before and after the carbon has been scrubbed or removed from the ambient air. The carbon capture adapter may capture and transform the carbon into secondary substances that may be useful unto itself, even further limiting waste and environmental damage. The carbon capture adapter will have all inputs, outputs, processes, and flows that meet all aspects of a closed loop system that is specifically designed for CCS.

    Abstract: Systems and methods determine a filter efficiency of a fluid filter. A characteristic of fluid flow of a fluid is monitored at a first point and at a second point on a flow path of a fluid filter. A particle absorption level of the fluid filter is determined that is a difference in the characteristic of the fluid flow at the first point and the second point. The particle absorption level of the fluid filter is at a particle absorption saturation level based on the difference in the characteristic of the fluid flow at the first point and the second point. The particle absorption saturation level is an indicator that the particles retained by the fluid filter is decreased and replacement of the fluid filter is required to increase the particles retained by the fluid filter to be above the particle absorption saturation level.
