ro booster pump 150 gpd - 0 views

  •  
    Most Reverse Osmosis membranes have ideal minimum pressure such as 50 psi or 60 psi. When the pressure is insufficient the RO system will generate less drinkable water at a low purify effect. The 150 gpd ro booster pump will increase 75 psi pressure. The RO pump can be used in a water purifier of 150 gallons per day. The RO Booster Pump 150 gpd can generate more high-purity freshwater with less rejected water. Commonly used either to pressurize water from an atmospheric tank, to deliver purified water to a specific point of use, or simply to increase pressure when required. This ro booster pump 150 GPD is designed for both intermittent duty and continuous operation.

6 Ways to Honor the Learning Process in Your Classroom | Edutopia - 0 views

  • Roughly put, learning is really just a growth in awareness.
  • While morsels of information -- math theorems, for example -- may not change, the context in which students use them do change. Which in turn changes how we consider and use that morsel.
  • Even what we call facts -- significant historical dates, labels for ethnic groups, causes and effects of cultural movements -- all change endlessly, if not in form (how they're discussed), then in meaning and connotation (what we think of them).
  • ...10 more annotations...
  • And thus changing how students use this skill or understanding. And thus changing how we, as teachers, "teach it."
  • This could be thought of as depth of understanding, a term that produced a depth of knowledge (DOK) framework for measuring understanding which is still used in many districts. Bloom's Taxonomy (1) or even the TeachThought Learning Taxonomy (2) are all tools to help evaluate understanding -- how well a student "gets it."
  • 1. Use Learning Taxonomies
  • 2. Use Concept Maps
  • Have students map, chart, diagram or otherwise visually represent their own learning pathways and changes in their own understanding.
  • 3. Use a Variety of Assessment Forms
  • 4. Build Metacognition into Units
  • Prime the pump by assigning students quick writing prompts about their own thinking.
  • 6. Connect Students to Networks
  • As students connect to networks, the learning process will plug them in, not just to one teacher, or 25 classmates, or eight texts, but to something much larger -- and more able to interact with students organically.
